Scale lines: 1 mm. Type material. Holotype : BRAZIL : Acre : ♂ , Rio Branco , Estação Experimental de Catuaba ( ‑10.0733 , ‑67.6239 ), January–April 2011 , M. R . B. Andrade leg. ( UFMG 10165 ). Etymology. The specific name refers to the type locality. Vila Grande Quinari is the original name of Senador Guiomard, and according to some of the older residents is a reference to a tree called Quinaquina, from which leaves are used to make tea against fevers and other illnesses; noun in apposition. Diagnosis. Males of M. quinari spec. nov. resemble those of M. tambor spec. nov. ( Figs 253–256 ) and M. vanini spec. nov. ( Figs 285–288 ) by the palp with embolus with long, distad, laminar subdistal projection and barely conspicuous membranous region (see Fig. 101 ). They are distinguished from both species by the RTA, distally tapering and bearing small triangular dorsal branch at base ( Fig. 240 ) (RTA distally blunt and without additional branches in M. tambor spec. nov. and M. vanini spec. nov. ). Females are unknown. Description. Male ( holotype ): Total length 11.4. Prosoma 5.3 long, 4.8 wide. Opisthosoma 6.0 long, 3.3 wide. Eyes: diameters: 0.45, 0.36, 0.30, 0.35; interdistances: 0.30, 0.10, 0.43, 0.50, 0.32, 0.20. Legs: I: 28.9 (8.6, 2.9, 8.3, 8.7, 2.1); III: 21.5 (6.4, 2.4, 5.7, 5.4, 1.6); IV: 24.0 (7.1, 2.2, 6.2, 6.6, 1.9). Spination follows the generic pattern except tibiae I–II: d1-0-1; tibiae III–IV: d0. Palp: PTA subtriangular, distally rounded, wider than long; RTA 1.7 times longer than wide (retrolateral view), irregularly conical; subtegulum visible between 8:30–10 o’clock in ventral view; tegulum slightly depressed close to conductor base; conductor widest at base, distally fanned; embolus subdistally curved with subdistal projection 1.5 times longer than wide ( Figs 238–241 , 245–247 ). Female: unknown. Distribution. Only known from the type locality ( Fig. 319 ).
